The SFK 655 hand block come with three different grit sizes. It can be used almost anywhere – at home, for car and motorcycle care or in the workshop. Craftsmen and do-it-yourselfers rely on it for their cleaning and finishing applications.

The product has been designed for hand sanding. It is suitable for work on:
paint,glass,stone,wood,plastic,leather and metals

Why choose the hand block SFK 655?

One major benefit of this abrasive block certainly lies in its suitability for universal use. It always offers the abrasive that is right for the job – regardless of the material. The silicon carbide grains bonded in plastic produce a substantially finer surface structure compared to abrasives that rely on a different type of bonding. This is why this abrasive block is preferred by many for cleaning and finishing. Examples of in the home include the cleaning of the underside of irons or cleaning stainless steel sinks. It is also used for rust removal in small spots on vehicles. The hand block is most effective when used in combination such cleaning agents as water or soap / such additives as petroleum or pastes.

Why is the abrasive hand block referred to as an elastic abrasive?

The abrasive grain used for the hand block is silicon carbide, which is bonded with plastic. The result is a structure that is more elastic compared to ceramic or synthetic resin bonds. This elasticity keeps roughness at a minimum and ensures that there are next to no changes to the geometry of the workpiece. Another factor of decisive impact on the scratch pattern – besides the abrasive grain – in the bonding. While exceedingly hard, the silicon carbide used is not particularly tough. Its crystalline structure makes the grit sharp-edged, yet brittle. Sensitive to breakage, the material causes micro-wear of the grit. When used for cleaning and finishing, the hand block will therefore remain usable until it is worn out completely. Since made synthetically, the grit is guaranteed to deliver uniform quality and defined characteristics.


The benefits at a glance

Wide range of applications
Our flexible abrasives, including our specialised R-Flex products, are particularly well-suited for finishing and cleaning as well as polishing all kinds of materials and have proven themselves time and again in the aviation industry or during the production of surgical instruments.

Adaptive aggressiveness
Since we offer different binding hardnesses ranging from soft to tough/hard as well as various grit types and sizes, the user can adapt the aggressiveness of our flexible abrasives perfectly to the application at hand.

Most refined surfaces
The finished surfaces produced by our flexible abrasives are much more refined than surfaces subjected to ordinary abrasives with a resin or ceramic bond. The elastic and resilient integration of the grit ensures that the roughness values and the changes in geometry introduced to the work piece are kept to a minimum.
